Mengnuan Wan (蒙暖 Wan or Mengnuan ワン) is one of the pre-made deceased ancestral Sims who resided during her lifetime in Riverblossom Hills, the neighborhood shipped with The Sims 2: Seasons. She was the wife of Xiaotien, the mother of Tianrong, and the grandmother of Patricia. She has personality points and interests, something not every ancestral Sim has. She is completely resurrectable, even though she doesn't have a grave.
Mengnuan has the Popularityaspiration, and the Geminizodiac sign. As far as personality, she is quite outgoing and very active, but she is a little bit sloppy, as well as being very grouchy and serious.
According to Mengnuan's SimDNA in SimPE, her hair was red before it turned gray. According to her age data, she had 14 days left in the elderlife stage when she died. Her facial structure is seemingly identical to the 17th Maxis face template in Create a Sim.
